I agree and the fact that they are trolling that it's not the best and most OP thing in the game currently while everything gets a nerf is just dishonest and shameful, i dont want their gameplay to change, by all means let them keep their baseline, but make everything else compliment the class instead of nerfing everything around it, so others can have fun engaging gameplay loops
A big point you're missing is mages will continue to get additions to their class through new magic schools.
Players with foot fighters get new materials (?) and weapon types. Maybe we'll see things like overhead strike, dual strike, etc. But I wouldn't hold my breath.
